Delaware has been granted a state registration (24c) for use of Dual Magnum in spinach. Growers in other states need to check with officials to ensure you have this registration. A few reminders: rate is 0.33 to 0.67 pt/A to the soil surface as a preemergence application i.e. prior to crop and weed emergence. Dual will not control emerged weeds. Irrigating spinach within two days of Dual application will ensure it gets moved into the soil. Restrictions: (1) Do not mechanically incorporate. (2) Do not apply this product through any type of irrigation system. (3) Only one application of Dual MAGNUM is permitted per spinach growing season. (4) Do not exceed more than 0.67 pt/A Dual MAGNUM. (5) Do not harvest with 50 days of application. Dual can cause injury to spinach and end user or grower accepts the risk of crop injury.
